Plasma, Oxyfuel, Alloy and Hardfacing<br />
Course Description<br />
Designed to instruct welders in welding safety, plasma cutting and<br />
gouging, the oxyfuel process, alloy theory and applications, and<br />
hardfacing. Additionally, various welding processes and techniques<br />
will be discussed as it relates to these topics. The course lasts 2<br />
weeks, involving approximately 60 hours of booth instruction, lecture<br />
and practice.<br />
Course Content<br />
Week 1<br />
• Learn fundamentals of oxy-fuel brazing (OFB) and oxyfuel welding<br />
(OFW). Discuss the use of welding vs. brazing vs. soldering.<br />
• Learn general theory and use of preheating along with hands-on<br />
experience utilizing Tempil sticks.<br />
• Learn the AWS numbering system, selection of proper brazing rods<br />
and fluxes, and troubleshooting of the oxyfuel process.<br />
• In addition to a comparison between carbon arc gouging vs.<br />
plasma arc gouging, discuss the operation of plasma cutting along<br />
with standard troubleshooting and operational techniques.<br />
• Learn fundamentals of metal identification including the AISI &<br />
ASTM designations as well as steel trade names.<br />
• Discuss low carbon, medium carbon, high carbon and alloy steel<br />
chemistry according to AWS D1.1 welding code.<br />
• Determine preheat and discuss carbon equivalent, heat input<br />
(Joules) and heat-treating including tempering, annealing,<br />
normalizing and stress relieving.<br />
• Learn fundamentals of hardfacing and 6 basic types of wear while<br />
using different welding processes: SMAW, FCAW, SAW and OFW.<br />
30 Clock Hours: Lab - 25, Class - 5<br />
Week 2<br />
• Learn fundamentals of cast iron including types of cast iron and<br />
repair procedures utilizing nickel and steel based electrodes as<br />
well as oxyfuel brazing (OFB) for cast iron repair.<br />
• Learn fundamentals of stainless steel including the AISI numbering<br />
system, AWS classification system of electrodes, and carbide<br />
control.<br />
• Use -15, -16, and -17 stainless stick electrodes to perform welds on<br />
stainless steel in all positions.<br />
